%X 【】　目的　探讨肝脏血管平滑肌脂肪瘤（hepaticangiomyolipoma，HAML）的多层螺旋CT影像学表现特征及其与病理学基础的相关性，以进一步提高CT诊断的准确性。　方法　收集2008年11月-2010年12月经手术病理证实的16例HAML患者。所有患者均行螺旋CT平扫及动脉期、门脉期增强检查，重点观察HAML的分型及其相应CT表现及影像-病理的相关性。　结果　16例患者共20个病灶，19个为稍低密度病灶，其中11个病灶内可见明显的脂肪密度影；1个为稍高密度病灶。动脉期所有病灶均有不同程度的强化表现，15个病灶内可见到较明显条状及扭曲的血管影。门脉期15个病灶有持续强化。　结论　多层螺旋CT能准确反映HAML的分型及其病理特征，对临床表现不典型患者的诊断和鉴别诊断有较大诊断价值。【Abstract】　Objective　TodiscussthecorrelationbetweenthefeaturesofmultislicespiralCTresultsforhepaticangiomyolipoma(HAML)andtheirpathologicalbasis,andtofurtherimprovethediagnosticaccuracythroughCTexamination.　Methods　SixteenHAMLpatientsdiagnosedpathologicallybetweenNovember2008andDecember2010inourhospitalwereenrolledinourstudy.Allpatientsunderwentmulti-slicespiralCTscanningofpre-andpost-contrastarterialphase,andportalvenousphase.FocuswasputonobservationofHAMLtypesandtheircorrespondingmanifestations,andthecorrelationbetweenCTimagingandthepathologicbasis.　Results　Therewere20lesionsinthe16patients.Amongthe19hypodenselesions,11wereclearlyseenwithfatdensityshadow.Oneoutofthe20lesionsshowedasslightlyhyperdense.Onthearterialphasescanning,alllesionsshowedenhancement,andobviousvascularshadowcouldbeseenin15lesions.Ontheportalvenousphase,15lesionscontinuedtostrengthen.　Conclusions　Multi-slicespiralCTcanaccuratelyreflecttheclassificationofHAMLanditspathologicalfeatures.Ithasagreatvalueinthediagnosisanddifferentialdiagnosisofpatientswithouttypicalclinicalmanifestations.
